  • Subjects must be in general good health, i.e., they must be free of any clinically significant disease (other than SAR) that would interfere with study evaluations.
  • Subjects must understand and be able to adhere to the dosing and visit schedules, and agree to report concomitant medications and adverse events to the Investigator or designee.
  • Subjects must have at least a positive history, self-reported history of signs and symptoms is acceptable, of recurring seasonal allergic rhinitis
  • Subjects must be clinically symptomatic with SAR at Visit 2 (Baseline): the total (nasal + non-nasal) symptom score must be >=8 points with a nasal congestion score of >=2, and the non-nasal symptom score must be >=2. Subjects may be rescheduled up two additional times for the qualifying visit if they do not meet the minimum symptom scores.
  • Women of childbearing potential must have be negative pregnancy history at Visit 1.

Exclusion Criteria:

  • Women who are pregnant or nursing.
  • Subjects who have not observed the designated washout periods for any of the prohibited medications.
  • Subjects with asthma who require chronic use of inhaled or systemic corticosteroids.
  • Subjects with current or history of frequent, clinically significant sinusitis or chronic purulent postnasal drip.
  • Subjects with rhinitis medicamentosa.
  • Subjects who have had an upper respiratory tract or sinus infection that required antibiotic therapy within 14 days prior to Visit 1 (Screening / Consent), or subjects who have had a viral upper respiratory infection within 7 days prior to Visit 1.
  • Subjects who have nasal structural abnormalities, including nasal polyps and marked septal deviation, that significantly interferes with nasal airflow.
  • Subjects who, in the opinion of the Investigator, are dependent upon nasal, oral or ocular decongestants, nasal topical antihistamines, or nasal steroids.
  • Subjects with a history of hypersensitivity to desloratadine or any of its excipients.
  • Subjects who are staff personnel directly involved with the administration of this study.
  • Subjects who have any current evidence of clinically significant hematopoetic, metabolic, cardiovascular, immunologic, neurologic, hematologic, gastrointestinal, hepatic, renal, psychiatric, cerebrovascular, or respiratory disease, or any other disorder which, in the judgment of the Investigator, may interfere with the study evaluations or affect subject safety.
  • Subject taking prohibited drugs listed in the study protocol are excluded from participation.
